Brown Rot (Monilinia fructicola) on Plums

Brown Rot fungus has infected all the plums on my plum tree this year. While there was a lot of blossom on the tree, perhaps a lack of pollinators early in the year meant that there were few fruits. And now these are all lost. The fungus spreads in the fruit, starting from blemishes caused by insect pests, such as Codling Moth.

800 Species

Some moth trapping this weekend brought my 800 species for the garden. Some of the highlights are shown below. Of the two new macros, the Dusky Sallow is a species from the Cotswolds liking drier calcareous habitats where its caterpillars live on grasses, whereas the Dun-bar is a woodland species needing deciduous trees. Apparently the caterpillars of the Dun-bar are partly carnivorous, augmenting their plant-based diet with caterpillars of other (and even sometimes their own) species.

Parasitic Wasp Eggs?

This caterpillar’s short life was interrupted by something. I thought at first a fungus, but after a bit of research I think the white blobs are actually insect eggs, probably from a parasitic wasp whose larvae are growing up inside the dead caterpillar. Yuck…

Dagger Fly: Empis opaca (#794)

This is my first “dagger fly” found in the garden; so-named because of its long beak. These come for nectar, as in this case on the flowers of a bramble, but are also predators. Courtship consists of the males offering prey to females, with the most favoured prey getting the girl. There are a few species, but this one with it’s reddish coloured legs (including the thighs) is I believe one of the commoner ones.

Marmalade Hoverfly

It’s been pretty poor for hoverflies so far this year, but this week there area lot of Marmalade Hoverflies on flowers around the garden. Hopefully a sign of more species starting to appear. The Golden Rod is soon coming into flower, which is usually a good place to see lots of hoverflies and other insects.

Burnished Brass

There are hardly any butterflies around during the day, but at night I seem to be doing pretty well catching moths. Last night I struck gold with a flashy Burnished Brass, a striking Shaded Broad-bar and a Scarce Footman, among seven new species. It’s not certain if the metallic marks on some moths are to deter or confuse predators, or if it’s just to look good.

Jackdaw in a Breakfast Cereal Box

This Jackdaw (Coloeus monedula) is on its way to the Vale Wildlife Hospital at Beckford. It is an adult bird, but a small one and not in good condition, even I think before the cat brought it in. Luckily it had managed to get away from the cat and didn’t seem too badly hurt, although it was unable to fly. I’m not sure how the cat got it as while there are plenty of jackdaws around, including nesting in the surrounding trees, they rarely come to the ground unless there are scraps there (which there weren’t this morning). The bird seemed in heavy moult, so maybe it was already grounded? Hoping the vets at the hospital can help it recover.

2nd July Micro Moths

These are some of the micro moths I caught recently. A couple of new species of tortrix moths, most of which seem to be found around orchards and fruit trees, of which there are many round here. Also it is the season for grass moths, so several of these appear in the catch.

2nd July Macro Moths

I caught a bumper haul of moths on Friday morning, following a still, warm & overcast night. This included four elephant hawk moths, and a several Heart & Date, Large Yellow Underwing, Uncertain, Flame, Buff Ermine and other commoner moths. Among these here are some of my favourites, including four new species of macro moths for my garden list.

Hawk Moths and More

More moths caught at the weekend, including Small and Large elephant Hawk Moths and Cloaked Minor, another new species.

Small Ranunculus (Hecatera dysodea, #777)

This nicely marked moth is a bit of a rarity as well. Small Ranunculus (Hecatera dysodea) was believed extinct in UK between 1914 and 1997, when it was found to be re-established in South-East England. This moth has been spreading North and West since, but there are still only a few records per year in Gloucestershire. This moth’s caterpillars are found on Prickly Lettuce, which itself found as a not-very-common weed on roadsides and disturbed ground.

Rosemary Beetle (Chrysolina americana)

These colourful beetles turn up on the lavender flowers at this time of the year. They are a non-native pest hailing originally from Southern Europe, and even though they were first found in UK as recently as the 1990’s they have managed to spread themselves right across the country. I don’t seem to get that many of them that they have become a pest.

New Moths - 23 June 2021

It was dry and still, but a bit cold overnight, so there weren’t too many moths in the trap this morning, but nonetheless three new species; a pug and two micros - all quite small and not very colourful.

The pug is a Currant Pug (Eupithecia assimilata), whose larval food-plant is (unsurprisingly) currant bushes. The large dark spots at the front of the wings and pale spots towards the trailing edge identify this species, which has 2 generations during the summer. Garden Pebble (Evergestis forficalis) is also double-brooded, favouring gardens and allotments where its caterpillars can be a pest on cruciferous plants (eg. cabbages). Finally the False Cacao Moth (Ephestia woodiella) has several similar relatives, but most of them are more likely to be found in food warehouses or your kitchen cupboards in the dried fruit, nuts or flour, than in the wild. Flying mostly in May-July, it seems to be becoming more common.

Pathway Grasses

These two grasses, including my first new species of plant this year, were growing on the gravel pathway leading to the house. Quite a big patch of Wall Barley (Hordeum murinum) has established itself along the alley. The other grass, Fern Grass (Catapodium rigidum) is a short and suprisingly stiff grass; again a common species along roadsides and paths.

Moth Trap Caddisflies

I caught a lot of caddisflies in the moth trap last weekend, including very many Long-horned Caddisfly (Mystacides longicornis), which I didn’t photograph for some reason. The ones I did capture on my phone included a couple of new species: the mottled Hydropsyche contubernalis and the paler Oecetis ochracea with its very long antennae. The fourth one appears to be a Limnephilus type caddisfly, but I’ve no idea which one as I didn’t find a photo yet that quite matches it.

New Moths this Weekend

Apart from the pugs, carpets and some others I covered separately, there was a great selection of moths in and around the moth trap this weekend. There were plenty that I also caught last year, but I can’t show them all, so here are the new species that I didn’t already mention in other posts. Even with all the great materials around on the web, especially the “Flying tonight” sites for Norfolk and Hampshire it still takes quite a time to go through and identify everything, and I’ve still got a few caddis flies and other non-moths I need to look at.
